Background: Randomized controlled trials (RCTs) evaluating the influence of personal protective equipment (PPE) on quality of chest compressions during cardiopulmonary resuscitation (CPR) showed inconsistent results. Accordingly, a meta-analysis was performed to provide an overview.Methods: Relevant studies were obtained by search of Medline, Embase, and Cochrane's Library databases. A random-effect model incorporating the potential heterogeneity was used to pool the results.Results: Six simulation-based RCTs were included. Overall, pooled results showed that there was no statistically significant difference between the rate [mean difference (MD): −1.70 time/min, 95% confidence interval (CI): −5.77 to 2.36, P = 0.41, I2 = 80%] or the depth [MD: −1.84 mm, 95% CI: −3.93 to 0.24, P = 0.11, I2 = 73%] of chest compressions performed by medical personnel with and without PPE. Subgroup analyses showed that use of PPE was associated with reduced rate of chest compressions in studies before COVID-19 (MD: −7.02 time/min, 95% CI: −10.46 to −3.57, P < 0.001), but not in studies after COVID-19 (MD: 0.14 time/min, 95% CI: −5.77 to 2.36, P = 0.95). In addition, PPE was not associated with significantly reduced depth of chest compressions in studies before (MD: −3.34 mm, 95% CI: −10.29 to −3.62, P = 0.35) or after (MD: −0.97 mm, 95% CI: −2.62 to 0.68, P = 0.25) COVID-19. No significant difference was found between parallel-group and crossover RCTs (P for subgroup difference both > 0.05).Conclusions: Evidence from simulation-based RCTs showed that use of PPE was not associated with reduced rate or depth of chest compressions in CPR.

Abstract Background: The efficacy of interventions for elderly patients with sarcopenia has received increasing attention. Exercise and nutrition have been recognized as effective treatments for sarcopenia in many studies. However, evidence-based support from relevant studies is still lacking. Methods: The PubMed, Embase, Cochrane Library, VIP, CNKI, and SinoMed databases were searched. The basis for the diagnosis of sarcopenia, general condition of the subjects, duration and methods of exercise/nutritional therapy, outcome indicators, and quality of evidence were evaluated, and a meta-analysis of differences in treatment outcomes between the groups from baseline to the end of each study was conducted. Results: A total of 1860 papers were screened, including six randomized controlled trials, and the effects of protein intervention under exercise conditions on muscle mass, strength, and function in elderly patients with sarcopenia were investigated. The results showed that protein supplementation under resistance exercise conditions had the following effects on elderly patients with sarcopenia: there was a significant difference in knee flexion and extension strength (p = 0.02), grip strength (p = 0.02), fat mass (p = 0.04), and normal pace and pace (p = 0.0008 and p = 0.0010, respectively) between the intervention group and baseline data.Conclusion: The meta-analysis revealed some positive effects of protein intervention treatment under exercise conditions on elderly patients with sarcopenia. However, the quality of evidence is low. High-quality randomized controlled trials should be conducted in the future to provide a better clinical basis. Keywords: Sarcopenia, Exercise, Proteins

Objectives. This study aims to assess the effectiveness and safety of moxibustion for the correction of nonvertex presentation.Methods. Records without language restrictions were searched up to February 2013 for randomized controlled trials (RCTs) comparing moxibustion with other therapies in women with a singleton nonvertex presentation. Cochrane risk of bias criteria were used to assess the methodological quality of the trials.Results. Seven of 392 potentially relevant studies met the inclusion criteria. When moxibustion was compared with other interventions, a meta-analysis revealed a significant difference in favor of moxibustion on the correction of nonvertex presentation at delivery (risk ratio (RR) 1.29, 95% confidence interval (CI) 1.12 to 1.49, andI2=0). The same findings applied to the cephalic presentation after cessation of treatment (RR 1.36, 95% CI 1.08 to 1.71, andI2=80%). A subgroup analysis that excluded two trials with a high risk of bias also indicated favorable effects (RR 1.63, 95% CI 1.42 to 1.86, andI2=0%). With respect to safety, moxibustion resulted in decreased use of oxytocin.Conclusion. Our systematic review and meta-analysis suggested that moxibustion may be an effective treatment for the correction of nonvertex presentation. Moreover, moxibustion might reduce the need for oxytocin.

N-3 polyunsaturated fatty acids (PUFAs) have been suggested to affect depressive disorders. This review aims to determine the effect of n-3 PUFAs on depressive symptoms in people with or without diagnosed depression. Medline, PsycINFO, and Cochrane CENTRAL databases were searched for randomized controlled trials (RCTs) assessing the association between n-3 PUFAs and depressive symptoms or disorders as outcomes. A random-effects meta-analysis of standardized mean difference (SMD) with 95% confidence intervals (CI) was performed. Twenty-five studies (7682 participants) were included. Our meta-analysis (20 studies) indicated that n-3 PUFA supplementation lowered depressive symptomology as compared with placebo: SMD = −0.34, 95% CI: −0.55, −0.12, I2 = 86%, n = 5836, but a possible publication bias cannot be ruled out. Subgroup analyses indicated no statistically significant difference by treatment duration of <12 vs. ≥12 weeks, presence of comorbidity, or severity of depressive symptoms. Nevertheless, beneficial effects were seen in the subgroups of studies with longer treatment duration and with no depression and mild to moderate depression. Subgroup analysis by eicosapentaenoic acid (EPA) dosage revealed differences in favor of the lower EPA dosage. Sensitivity analysis including studies with low risk of bias seems to confirm the overall result. Supplementation of n-3 PUFA appears to have a modest beneficial effect on depressive symptomology, although the quality of evidence is still insufficient.

Background: Several studies have suggested that exercise capacity and quality of life are reduced in patients with pulmonary hypertension (PH), and exercise-based rehabilitation can improve exercise capacity and quality of life in patients with PH. The aim of this study is to assess the efficacy and safety of exercise-based rehabilitation in patients with PH through a meta-analysis of randomized controlled trials. Methods: We searched PubMed, Embase, Medline, and the Cochrane Central Register of Controlled Trials up to November 2018. All randomized controlled trials (RCTs) comparing exercise capacity and quality of life between patients undergoing exercise-based rehabilitation and those undergoing non-exercise training were included. Data were extracted separately and independently by two investigators, and discrepancies were arbitrated by the third investigator. We used the random-effects model to analyze the results, the GRADE to assess the risk of bias in the included studies, and I ² statistic to estimate the degree of heterogeneity. Results: Nine RCTs are included, however, only seven RCTs were able to extract data. Including inpatients and outpatients, the total number of participants was 234, most of whom were diagnosed as pulmonary artery hypertension (PAH). The study duration ranged from 3 to15 weeks. The mean six-minute walk distance after exercise training was 51.94 metres higher than control (27.65 to 76.23 metres, n=234, 7 RCTs, low quality evidence), the mean peak oxygen uptake  was 2.96 ml/kg/minute higher (2.49 to 3.43 ml/kg/minute, n=179, 4 RCTs, low-quality evidence) than in the control group . Concluded: Our finding suggest that an exercise-based training program positively influences exercise capacity in patients with PH.

Background. A substantial proportion of patients undergoing colorectal surgery receive a temporary stoma, and the timing for stoma closure remains unclear. The aim of this study was to evaluate the safety and feasibility of early stoma closure (ESC) compared with routine stoma closure (RSC) after colorectal surgery. Methods. We comprehensively searched PubMed, Embase, and the Cochrane Library for randomized controlled trials that compared ESC and RSC after colorectal surgery. Results. A total of 7 randomized controlled trials with 814 enrolled patients were identified for this meta-analysis. There were no significant differences between the ESC and RSC groups regarding the complications of stoma closure (26.8% and 16.6%, respectively; odds ratio [OR]: 1.30; 95% confidence interval [CI]: 0.89-1.90; P = .17). A subgroup analysis was conducted by Clavien-Dindo grade of complication, and no significant difference was observed in any subgroup ( P > .05). However, the ESC group had a significantly higher risk of wound complications than the RSC group (17.6% and 7.8%, respectively; OR: 2.61; 95% CI: 1.43-4.76; P = .002), and the RSC group had more cases of small bowel obstruction than the ESC group (3.1% and 8.4%, respectively; OR: 0.37; 95% CI: 0.15-0.87; P = .02). Conclusions. ESC is a safe and effective therapeutic approach in patients who have undergone colorectal surgery; it is associated with a reduced risk of bowel obstruction but a higher risk of wound complications.

Virtual reality (VR), a technology that provides a stimulated sensory experience, has recently been implemented in various fields of medicine. Several studies have investigated the efficacy of VR on preoperative anxiety. The purpose of this meta-analysis was to validate whether VR could relieve preoperative anxiety in patients undergoing surgery. Electronic databases were searched to identify all randomized controlled trials (RCTs) investigating the effect of VR on preoperative anxiety. The primary outcome was defined as the preoperative anxiety scores. We estimated the effect size using the standard mean difference (SMD) with a 95% confidence interval (CI) using a random effect model. Ultimately, 10 RCTs, with a total of 813 patients, were included in the final analysis. Preoperative anxiety was significantly lower in the VR group than in the control group (SMD −0.64, 95% CI −1.08 to −0.20, p = 0.004). In a subgroup analysis, the preoperative anxiety scores were lower in the VR group than in the control group in pediatric patients (SMD −0.71, 95% CI −1.14 to −0.27, p = 0.002), whereas a significant difference was not observed between the two groups in adult patients (p = 0.226). The results of this meta-analysis indicated that VR could decrease preoperative anxiety, especially in pediatric patients.

BACKGROUND An increasing number of patients have received prophylactic or therapeutic oral anticoagulants (OACs) for thromboembolic complications of diseases. The use of OACs is associated with both clinical benefits and risks. Considering the challenges imposed by this class of drugs, as well as the enormous progress made in portable device technology, it is possible that technology-based interventions may improve clinical benefits for patients and optimize anticoagulation management. OBJECTIVE This study was designed to comprehensively evaluate the role of technology-based interventions in the management of OACs. METHODS We searched 6 databases—PubMed, EMBASE, Cochrane, Cumulative Index to Nursing and Allied Health Literature, Scopus, and PsycINFO—to retrieve relevant studies published as of November 1, 2019, to evaluate the effect of technology-based interventions on oral anticoagulation management. RevMan (version 5.3; Cochrane) software was used to evaluate and analyze clinical outcomes. The methodological quality of studies was assessed by the Cochrane risk of bias tool. RESULTS A total of 15 randomized controlled trials (RCTs) were selected for analysis. They reported data for 2218 patients (1110 patients in the intervention groups and 1108 patients in the control groups). A meta-analysis was performed on the effectiveness and safety data reported in the RCTs. Technology-based interventions significantly improved the effectiveness of oral anticoagulation management (mean difference [MD]=6.07; 95% CI 0.84-11.30; I<sup>2</sup>=72%; <i>P</i>=.02). The safety of oral anticoagulation management was also improved, but the results were not statistically significant. Bleeding events were reduced (major bleeding events MD=1.02; 95% CI 0.78-1.32; I<sup>2</sup>=0%; <i>P</i>=.90; minor bleeding events MD=1.06, 95% CI 0.77-1.44; I<sup>2</sup>=41%; <i>P</i>=.73) and thromboembolism events were reduced (MD=0.71; 95% CI 0.49-1.01; I<sup>2</sup>=0%; <i>P</i>=.06). In general, patients were more satisfied with technology-based interventions, which could also improve their knowledge of anticoagulation management, improve their quality of life, and reduce mortality and hospitalization events. CONCLUSIONS Using technology to manage OACs can improve the effectiveness and safety of oral anticoagulation management, result in higher patient satisfaction, and allow greater understanding of anticoagulation.

This meta-analysis aims to compare intravenous colistin monotherapy and colistin-based combination therapy against carbapenem-resistant gram-negative bacteria (GNB) infections. PubMed, Embase, and Cochrane databases were searched up to July 2018. Only randomized controlled trials (RCTs) evaluating colistin alone and colistin-based combination therapy in the treatment of carbapenem-resistant GNB infections were included. The primary outcome was all-cause mortality. Five RCTs including 791 patients were included. Overall, colistin monotherapy was associated with a risk ratio (RR) of 1.03 (95% confidence interval (CI), 0.89–1.20, I2 = 0%) for all-cause mortality compared with colistin-based combination therapy. The non-significant difference was also detected in infection-related mortality (RR, 1.23, 95% CI, 0.91–1.67, I2 = 0%) and microbiologic response (RR, 0.86, 95% CI, 0.72–1.04, I2 = 62%). In addition, no significant difference was observed in the subgroup analysis—high or low dose, with or without a loading dose, carbapenem-resistant Acinetobacter baumannii infections, and in combination with rifampicin. Finally, colistin monotherapy was not associated with lower nephrotoxicity than colistin combination therapy (RR, 0.98; 95% CI, 0.84–1.21, I2 = 0%). Based on the analysis of the five RCTs, no differences were found between colistin monotherapy and colistin-based combination therapy against carbapenem-resistant GNB infections, especially for A. baumannii infections.
